VII XVIII MDCCCCLXXXVIIII or VII (7) IIXX (20-2) IXMM (2000-11). Note that 1989 in Roman mumerals is not MCMLXXXIX as you might have expected. Alternative answer Contrary to the views expressed in the above answer the universally accepted method of writing 1989 in Roman numerals is MCMLXXXIX. IXMM completely contravenes the accepted rules for writing Roman numerals. According to the website Algebra.com "I can be placed before V and X but should not be placed before any larger numeral. X can be placed befiore L and C but not before D or M." MDCCCCLXXXXVIIII may be numerically correct but it is an unwieldy and little used way of writing MCMLXXXIX. Roman numerals read from left to right and always begin with the highest value symbol. While both MCMLXXXIX and MDCCCCLXXXXVIIII comply with this rule, IXMM, which begins with the symbol for 1, clearly does not.
